SHOE .A ND METHOD OF MAKING.

Application filed May 29, 1924. Serial No. 716,653.

To. all whom it may concern:

Be it known that we, J O'HN D. PRICE and .VVALTER. H. DRAKE, citizens ofthe United States, residing at-C leveland, in the county of Cuyahoga andState of Ohio, have invented certain new and useful Improve-- lnents inShoes and Methods of Making,

of which the following is a specification.

This invention relates to shoe construc tion and has for an obectto'provide a shoe of improved type and method of making the same.

- A further object of the invention is to provide a shoe embodying ametallic inner sole with improved means for attaching the upper andother related parts to the sole without perforating the metal innersole.

A further object of the invention is the method whereby the attachingmeans consisting of nails or other penetrating members, are insertedthrough certain of the leather or fabric parts and to clinch by en-'gagement with and against the metal inner sole.

With these and other objects in View, the invention comprises certainnovel steps in the process and certain novel parts, elements, units,combinations, interactions and functions of the article as disclosed inthe drawings together with mechanical and functional equivalents thereofand of the process involved as will be hereinafter more fully describedand claimed.

. In the drawings:

Figure 1 is a transverse sectional view through the body of a shoe, asfor instance across the ball of the foot showing in section the soleorganization and the means of attaching.

Figure 2 is an enlarged detail view of one side' of the attachment.

Figure 3 is an enlarged detail view of a modification.

Like characters of reference indicate corresponding parts throughout theseveral views.

The improved shoe, which, together with its method of manufacture, formsthe subject matter of this invention, comprises as a foundation an innersole 10 of some material analogizing metal of a relatively rigidconstruction attenuated to resiliency so that in its preferred form theinner sole would resemble a thin plate of highly tempered spring steel,it being understood,'0f

course, that all equivalents are included in the present invention.

This metallic plate is covered with an insulating cover 11 which willpreferably be some type of-leather, fabric or other flexible sheetmaterial being folded at the edges as indicated at 12 about the marginsof this metallic inner sole. An'upper, indicated conventionally at 13,is employed and the showing of this upper as asingle thickness ofmaterial is. not intended as any limitation upon the use of liningmaterial or other usual and ordinary or preferred combinations wherebythe upper conforms to requirements or meets the desideratum of users.

An insole 14 is employed which in the type shown at Figures 1 and 2 isskived down adjacent the edges as indicated at 15 so that the middle orinterior part of said insole is thinner than the marginal edgesindicated at 16 which serve the purpose of a welt strip' as will behereinafter more fully described. In this type of shoe, a filler 17 isemployed, the edges of which are skived at 18 complementary to theskiving 15 and between which skived portions the inturned edges of thefabric 11 and the upper 13 are embraced. Penetrating members, indicatedin the drawings as nails 19, are" employed by being driven through the.insole 14, through the inturned edges of the upper and insulatingfabric, through the filler and against the metal plate 10-, preferablyat an inclination as indicated at Fig ures 1 and 2 so thatthe end tendsto clinch as indicated at 20, it being obvious, of course,

that for this operation alast will be within the shoe so that the thinmetal plate 10 will have a firmer support for the clinching operation.As shown in this figure, the clinch 20 occurs in the filler 17. 1

In the type shown at Figure 3, the insole 14 is not skived down to bethinner at the interior than the exterior, in fact may be the samethickness or slightly thicker, as indicated at said Figure 3 and themarginal edges provided with a slot 21 into which the inturned edges ofthe fabric liner and the upper are inserted the same as between theinsole 14 and the filler 17. When so inserted, the nail 19 or otherpenetrating member is driven the same as shown at Fig ures 1' and 2clinching at 20 the same as in the process method. This type does awaywith the lamination of the filler and insole and provides a similar weltmargin 16. To this welt margin 16 or 16 the outer sole 22 is sewed inthe usual manner by the stitches As hereinbefore stated, the penetratingmembers which secure these parts together seem at the present time topoint to a preference for headed nails with attenuated points whichclinch as indicated, but it is to be understood that further use of theinvention may indicate the desirability of other or different type ofpenetrating members and the invention is broad enough to include anysuch penetrating members as are inserted upon such an inclinationrelative to the plane of the metallic insole as to be clinched by theirinsertion and thereby secure all of the several parts together in apermanent, inseparable organization.

It is again emphasized that by this construction the metallic plate 10is held in position in the shoe by the insulatin liner 11 which protectsthe foot from radiation from the metallic plate as one of its principalfunctions, while another and fully as important function is that itsmargins inturned serve to receive the penetrating members whereby themetallic plate is secured in the organization Without penetrating orperforation and the upper likewise and simultaneously secured in itsproper relation. The construction of the insole in the lamination formor in the integral form is a matter of choice or expediency.

What we claim to be new is:

1. The method of making a shoe consisting in folding the marginal edgeof an insulating fabric about the marginal edge of an imperforate solemember composed of rigid material attenuated to resiliency, insertingsaid marginal edge together with the marginal edge of the upper betweenspaced parts of an insole organization with the resilient plate restingdirectly upon said.

organization and inserting penetrating members at an inclination throughsaid insole organization, the inserted edges of said insulating fabricand upper, and clinching by impingement against the under side of saidresilient sole member.

2. The method of making a shoe consisting in folding the marginal edgeof an insulating fabric about the marginal edge of a sheet of materialcut to the proper dimensions of the shoe, composed of rigid materialattenuated to resiliency, folding said edge into an interstice adjacentthe edge of an insole structure together with the marginal edge of theupper and inserting penetrating members through said structure includingsaid inturned edges, and clinching said penetrating member against theunder side of said attenuated resilient sole member into and holding insaid insole structure.

3. A shoe construction, comprising an insole structure having adjacentits marginal edge an iuterstice directed toward the interior of thestructure, a plate disposed upon said structure composed of rigidmaterial attenuated to resiliency, an insulating covering for said platehaving its edge inserted into said interstice, an upper having itsmarginal edge inserted. into said interstice together with the marginaledge of said insulating material, and a penetrating member insertedthrough said structure and said marginal edges and having a clinchformed against the under side of said resilient plate and occupying aposition within the material of said structure.

4. A shoe construction comprising an insole properly proportioned toemploy its marginal edge as a welt, a filler disposed upon the insoleand smaller in area than the insole, a plate disposed upon the filler ofsubstantially the same area, composed of rigid material attenuated toresiliency, an insulating sheet disposed upon the attenuated rigidmember and having its marginal edge turned under and inserted betweenthe filler and the insole, an upper having its marginal edge insertedbetween the filler and the insole along with the marginal edge of theinsulating sheet, penetrating members inserted at an angle to the planeof the attenuated plate, and a clinch formed upon said penetratingmember against said attenuated member, and disposed within the materialof the filler, said penetrating memher being inserted through theinturned marginal edges of the insulating sheet and upper. y

In testimony whereof we affix our signatures.
